Geographic Information System Trivia Quiz

CGIS was created in 1960.

Slope is the correct answer because it refers to the steepness of a terrain. Slope is the measure of how steep or gradual a surface is, usually measured as the vertical rise over a horizontal distance. It is an important factor in determining the difficulty and safety of traversing a terrain, as steeper slopes can be more challenging to navigate.

Roger Tomlinson is acknowledged as the father of GIS. He is credited with developing the first true GIS in the 1960s. Tomlinson's work laid the foundation for the use of computer-based systems to analyze and manage geographic data. His pioneering efforts in the field of GIS have had a significant impact on various industries, including urban planning, environmental management, and transportation.

The correct answer is Open Geospatial Consortium. The Open Geospatial Consortium (OGC) is an international organization that develops and promotes open standards for geospatial data and services. These standards enable interoperability and seamless integration of geospatial technologies, allowing different systems and applications to communicate and share geospatial information effectively. The OGC plays a crucial role in facilitating collaboration and innovation in the field of geospatial technology.

Aspect is the term that defines the direction a unit terrain face is facing. It refers to the compass direction that a slope is facing, such as north, south, east, or west. Aspect is an important concept in geography and geology as it influences various factors like temperature, sunlight exposure, and vegetation distribution on a slope. It helps in understanding the physical characteristics and behavior of a terrain face.

The first operational GIS was developed in Canada.

The computer mapping application was improved upon to create the CGIS. This suggests that the CGIS is an enhanced version of a computer mapping application, implying that it includes additional features, functionality, or improvements compared to a standard mapping application.

Digitisation is the most common method of data creation because it involves converting analog information into a digital format. This process allows for easier storage, manipulation, and analysis of data. Digitisation is widely used in various fields such as document management, image processing, and data entry. It involves scanning physical documents or converting analog signals into digital form, making it a prevalent method for creating new data.

Interpolation is the correct answer because it refers to the process of creating new data points within a set of known data points. In the context of the question, interpolation is used to create surfaces by using collected data to estimate values at unmeasured locations. This technique is commonly used in various fields such as geography, cartography, and computer graphics to fill in missing or incomplete data points and create smooth surfaces.

Ground measurements are related to Geostatistics. Geostatistics is a branch of statistics that deals with the analysis and interpretation of spatial data, including ground measurements. It involves studying the spatial correlation and variability of data in order to make predictions and estimates about unobserved locations. Therefore, ground measurements are directly related to Geostatistics.
